A man suspected of driving the wrong way on a Vermont interstate and causing a fiery crash that killed five teenagers has been charged with five counts of second-degree murder.

Police said 36-year-old Steven Bourgoin crashed into the teens' car in Williston, then stole a police cruiser before crashing it into at least seven other vehicles late Saturday night.

Police on Tuesday served an arrest warrant on the hospitalized Bourgoin for use of the cruiser. On Thursday, the state filed five counts of second-degree murder against him in the teens' deaths. Public defenders working on the case did not immediately return phone calls or emails seeking comments.

Bourgoin is to be arraigned Friday in the hospital, where his condition has been upgraded from critical to good.
